Floribunda rose plant named ‘Meijecycka’

ABSTRACT

A new and distinct Floribunda rose plant is provided which abundantly and nearly continuously forms attractive yellow cup-shaped blossoms commonly displaying approximately 5 to 7 petals. The growth habit is bushy and the adult plant commonly assumes a generally hemispherical configuration. The plant exhibits very strong vegetation, with green semi-glossy foliage that contrasts nicely with the yellow bossom coloration. The blossoms display no fragrance. The new variety is well suited for growing as attractive ornamentation in parks and gardens.

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: cv. Meijecycka.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) was a productof the cross of ‘The Fairy’ variety (non-patented in the United States)and an unnamed seedling (non-patented in the United States). The maleparent (i.e., the pollen parent) was the product of the cross of the‘Kortikel’ variety (non-patented in the United States) and the‘Macshana’ variety (U.S. Plant Pat. No. 5,427). The parentage of the newvariety can be summarized as follows:(‘The Fairy’×Unnamed Seedling)×(‘Kortikel’×Macshana’).

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new Floribunda rose plant of the presentinvention:

-   -   (a) exhibits a bushy adult growth habit that commonly is        generally hemispherical in configuration,    -   (b) abundantly and nearly continuously forms attractive yellow        cup-shaped blossoms commonly displaying approximately 5 to 7        petals,    -   (c) forms very strong vegetation with attractive green        semi-glossy foliage that contrasts nicely with the yellow        blossom coloration, and    -   (d) is well suited for growing as ornamentation in parks and        gardens.

The new variety well meets the needs of the horticultural industry andcan be grown to advantage in the landscape where attractiveornamentation is desired. The attractive yellow blossoms commonlyinitiate blossoming early in the season.

The new variety can be readily distinguished from its ancestors. Forinstance, ‘The Fairy’ variety displays dissimilar light pink blossoms.The blossoms of the ‘Kortikel’ and ‘Macshana’ varieties commonly possessa substantially larger number of petals than the new variety. Theproduct of the cross of ‘The Fairy’ and unnamed seedling (non-patentedin the United States) displays very pale yellow blossoms and a slowrepeat blooming characteristic. The product of the cross of the‘Kortikel’ and ‘Machana’ varieties (non-patented in the United States)displays blossoms having a dissimilar very intense yellow coloration.The new variety also can be readily distinguished from the ‘Medresia’variety (non-patented in the United States) and the ‘Meibaltaz’ variety(U.S. Plant Pat. No. 8,449). The ‘Medresia’ and ‘Meibaltaz’ varietiesdisplay blossoms having considerably more petals. Also, the blossomcoloration of the ‘Meidresia’ variety is more intense, and the‘Meibaltaz’ variety exhibits a more upright growth habit.

The new variety has been found to undergo asexual propagation in Franceat Le Cannet-des-Maures, by a number of routes, including budding,grafting, and the use of cuttings. Asexual propagation by theabove-mentioned techniques in France has shown that the characteristicsof the new variety are stable and are strictly transmissible by suchasexual propagation from one generation to another. Accordingly, the newvariety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘Meijecycka’.
